US Patent 7924226 Tunable antenna

The invention refers to an antenna comprising: a conducting trace (15, 20), said conducting trace (15, 20) defining a curve (1, 4, 5, 6, 6′, 6″, 8), said curve (1, 4, 5, 6, 6′, 6″, 8) including two or more feeding points (16a, 16b, 16c, 17, 18, 19), a portion of said curve (1, 4, 5, 6, 6′, 6″, 8) being shaped according a geometry selected from a group of geometries including a space-filling curve, a grid-dimension curve, a box-counting curve and a contour curve or the curve (1, 4, 5, 6, 6′, 6″, 8) or a portion of said curve having a shape of a multilevel structure. Further the invention refers to a related SMD component, an IC-package, a wireless device and a method for contacting an antenna.
